SECTIONED CONTAINER AND BLANK THEREFOR William M. Strange, Neenah, Wis, assignor to John Strange Carton Company, Menasha, Wis, a corporation of Wisconsin Filed Nov. 16, 1959, Ser. No. 853,078

6 Claims. (Cl. 229-27) This invention relates to an encloseable container and blank therefor and more particularly to a container having partitions and closed, flush ends therefor.

It is an object of my invention to provide an elongate container having closed, flush ends to facilitate overwrapping. I

It is another object of my invention to provide a blank for a container wherein end tabs are in looking engagement.

It is a further object of my invention to provide an end structured container having increased rigidity thereby.

It is still another object of my invention to provide a single blank having lateral portions wherein end tabs are integral with at least three of said portions for forming a container having locked, flush ends.

These and other objects and .advantages of my invention will more fully appear from the following description, made in connection withthe accompanying drawings, wherein like reference characters refer to the same or similar parts throughout the several views and in which:

-Figure 1 is a perspective view of my container in a partially closed condition;

Figure 2 is a sectional view taken at 2--2 of Fig. l with the container completely closed;

Figure 3 is a section view taken at 3--3 of Fig. 1;

Figure 4 is a plan view of the blank of the container of Fig. l; 1

Figure 5 is a rear elevated view of the blank of Fig. 4 in a fiat partially folded condition; and

Figure 6 is an end view of the partially folded blank of Fig. 5.

With continued reference to the drawings, Fig. 1 dis closes an elongate container 10 folded from a paperboard blank 11. The container 1% has two article holding sections 12 and 13 separated by a partition 14. The container 10 also comprises a front panel 15, a back panel 16 adhesively secured to an overlap back panel 17 (Fig.

.4), end covers 18 and 19, a bottom panel 20, a cover panel 21, cover panel tabs 22 and 23, and a multiple partition panel 24. Said panels are delineated one from the other by score or fold lines 25, 26, 27, 28, 29 and 30' (Fig. 4). Additionally score or fold lines 29 and 3% cut through the blank 11 at portions 29a and 30a for reasons to be described hereinafter.

To fold the blank 11 into a container or carton, adhesive material may be applied either to the face of back panel 16 or to the underside of overlap back panel 17, and in the preferred embodiment I have so applied adhesive material.

By folding the panels along their score or fold lines panel 17 confronts panel 16 along its length, and by reason of adhesive material will adhere thereto. The blank 11 will, at this first folding, be in the condition shown in Fig. 6. The blank 11 can then be flattened as shown in Fig. 5, in which flattened condition it can easily 2 ,970,738 Patented Feb, 7, 1961 be shipped or stored, either singly or with a plurality of other similarly folded blanks.

However, to form the container 10, slight pressure, as by hand, is applied at fold line 29 as best seen in Fig. 6. The application of pressure along the fold line, causes multiple partition panel 24 to become substantially parallel with bottom panel 20, and front panel 15 becomes substantiallyparallel with adhered back panels 16 and 17, thus resulting in the substantially rectangular shape of the container as shown in Fig. 3. a

It is now expedient to describe multiple partition panel 24 in more detail, with particular reference to Fig.4. As hereinabove mentionedmultiple partition panel24 is delineated from the other panels by score or fold lines 29 and 30, and cuts 2% and 30a. 'Normal to. cuts 29a and 3% are cuts 31 which divide partition panel 24 into partition members 32, 33, 34 and 35. End covers 18 and 19, integral with partition panel 24 are provided with locking end tabs 18a and 19a respectively and score or fold lines 36 and 37 facilitate the folding of said end tabs. It should also be noted that portions of fold lines 36 and 37 comprise cuts 36a and 37a which facilitate locking of end covers 18 and 19 as will be described hereinafter.

Additional score or fold lines 38, 35, 40, 41, 42, 43, 44, 45, 46 and 47 are provided in partition panel 24. Each of score lines 3847 may be provided with a central cut 48 to facilitate folding on lines 33-47.

Having described partition panel 24, the folding operation of blank 11 may now be continued. With back panel 16 and 17 adhesively secured, and panels 15, 20, and 24 in a substantially rectangular relationship, the partition members 32-35 are each pushed downwardly as viewed in the drawings, thereby folding along fold lines 39, 42, 43, and 46 respectively. As partition members 32-35 contact bottom panel 20, the members 3235 fold at lines 40, 41, 44 and 45 respectively, thereby placing the partition members 32-35 substantially normal to bottom panel 20, and the lower portions 32a-35a of said partition members abut bottom panel 20 at substantially right angle to said partition members 32-35. There is sufiicient engagement of lower portion members 32a-35awith bottom panel 20 to maintain portion members 32-35 substantial- 1y normal to bottom 20. Further, it is seen that the partition members 3235 are coextensive with the width of bottom 20, and the space between folded panels 17 and 15 to provide a lateral rigidity to the folded blank 11.-

Prior to the folding of end covers 18 and 19 and locking end tabs 18a and 19a, front panel end tabs 15a and 15b and back panel end tabs 17a and 17b are infolded toward each other in substantial alignment with the ends of bottom panel 20. End covers 18 and 19 are then folded on lines 38 and 47 to overlap said front and back panel end tabs. Locking end tabs 18a and 19a are inserted between front and back panel end tabs and bottom panel 20. With the locking end tabs 18a and 19a so inserted, front and back panel end tabs lock in cuts 36:: and 37a to secure the folded condition of end covers 18 and 19. The end covers so secured present a flush, rigid end for the container 19 which facilitates overwrapping of said container.

The container 10 is now ready for closure by a cover panel 21 and cover panel tabs 22 and 23. The cover panel 21 is folded along line 26, and tabs 22, 23 are folded along line 25. Tabs 22 and 23 are inserted into cut 30a so that the tabs overlap against an inner surface of front panel 15, and cover panel 2]; completely encloses said container. Tabs 22 and 23 are spaced one from the other to pass partition members 33 and 34 and abut thereagainst upon insertion.

It will be noted that end covers 18 and 19 lie spaced from respective partition members 32 and 35 in the completed container and provide a protective cushioning effect against endwise shifting of objects which may be placed therein. Similarly partition members 33 and 34 are spacedv apart and provide a cushioning effect against convergence of objects placed in contact with the respective members.

Thus I have described the folding of a stiff, foldable, flexible blank into a container, wherein the container is provided with a plurality of article holding sections, and the ends of said container are, of flush, rigid, locked constructions.

It will, of course, be understood that various changes may be made in the form, details, arrangements and proportions of the parts without departing from the scope of my invention as set forth in the appended claims.

What I claim is:
